After reading this thread I got on the web site link Forrest provided and the G 614 tires are on sale for $218. I ordered four for our 09 3600 RL. Been down this road with SOB trailer - two blow outs, one tread separation, one tread deterioration (chunks missing) and one starting to go, body work to both sides of the trailer, propane lines torn out, etc. I've only pulled the trailer from the dealer to the RV campground where we live and I'm not taking the chance. Will change out the tires as soon as they arrive.
Anybody want to buy a set of almost new Freestar tires?
